Jonghyun of CNBLUE has put a cover to EXO's 2015 winter song, 'Sing for You.'

On December 28th, the idol took to his Instagram and uploaded two clips of him singing to EXO's 'Sing for You.' While strumming to his guitar, Jonghyun sang the song as if it's meant to be his own song. Needless to say, fans were all excited to listen to the cover.

Not only that, the fact that Chanyeol give the post heart makes fans hyped even more. Jonghyun and Chanyeol are close as friend -- they even once had a trip to Japan together with Block B's Zico, actor Choi Taejoon, and another friend of them.
